As the last book isn't written yet - we can still hope to discover that:
- Jon is the Son of Rhaegar Targaryen and Lyanna Stark;
- Daenary's will become Queen of the Seven Kingdoms, conquer the Free Cities, and start a Pax-Daenaryana;
- Ramsey Snow/Bolton dies a gruesome death;
- Sansa Stark gets the receipt for all the misfortune she's caused her family - or alternatively returns to her Husband Tyrion;
- Arya Stark becomes the new Head of House Stark;
- The Nightswatch regains much of it's former Glory and High-Standing with the People, and rules are changed a bit;
- Jorah Mormont becomes the new Lord Commander of the Nightwatch;
- Bran Stark becomes some sort of whatever for the Northern People for his abilities to control animals;
- Tyrion Lannister will become new Head of House Lannister;
- Samwell "Sam" Tarly evolves into a Grand Maester;
- Petyr "Little Finger" Baelish get's thrown out of the Moon Door;
- Rickon Stark gets over his unrulyness and becomes more like his Father and Brother Robb;
- Varys is finally explained and then exiled;
- Sandor "The Hound" Clegane is discovered to be alive and lives the life of a Monk;
- Jon gets to bang and marry Daenarys - though then again, if she is his Aunt, that would be incest - and couldn't be shown on TV... (though it would be in line with Targaryen Royal Traditions to marry Brothers and Sisters, in this case Nephew and Aunt, who are the same age though).
